1) Devils Tower National Monument: Devils Tower is a large monolith and is 386 meters high. The summit is located at 1558 meters above sea level. This striking geological phenomenon, which was seen in the film Close Encounters of the Third Kind by Steven Spielberg from 1977, is located in the northeast corner of Wyoming. The hills of this 545 ha park are covered with pine trees, deciduous trees and prairies with grass. The entrance to the park is $ 20.00 per car with all its passengers and is valid for 7 days. Despite this is a National Monument you can also use the America the Beautiful pass here.

2) Trails: If you visit Devils Tower National Monument follow the trails that have been specifically set out for visitors. It is forbidden to leave these paths. The Devils Tower and surroundings are sacred ground for the Native Americans and you will also destroy the beautiful nature. Please adhere and respect nature and the Native Americans.

3) Wildlife: Unfortunately, there are still people who feed the wildlife. I have seen this with my own eyes that prairie dogs are fed with marshmallows. This is forbidden! You are not helping the prairie dogs because you make them dependent on humans and they lose their instinct, making them easier prey for their natural enemies. Here too, the rule is to respect anf view the wildlife from a distance.

The most remarkable feature of the landscape in the north-east of Wyoming is the giant rock pillar in the Devils Tower National Monument, about 28 miles (45 km) nortwest of the town of Sundance on Highway 2.

The Devils Tower, a giant monolith that became America's first national monument in 1996, has a height of 26 meters from its base; and calculated from the water level of the flowing Belle Fourche River, the height is even 386 meters.

The stone mass has such an attraction that tribes (native americans) on the northern plains considered the stone mass as sacred.The details of the origin myths of the Lakota, Kiowa and Cheyenne differ, but it always comes down to seven sisters who are attacked by a bear. The stripes on the stone represent the claws of the bear, and the sisters were thrown into the air and became the Pleiadians (a star group also called the 'seven sisters').

Geologists apply a different theory: it concerns igneous rock that came up and hardened through softer sediment layers. The rock mass stands in the middle of the 550 ha Devils Tower National Monument, that attracts climbers by a magnet. (In June, they will not climb the massive rock out of respect for the Native ceremonies). The park has 7 miles (11 km) of trails, including a route through the forest around the tower itself.

Millions of film lovers have seen the Devils Tower in the science fiction film Close Encounters of the Third Kind by Steven Spielberg (1977), in which the area around the rock served as a landing place for a spaceship.
